The formula for calculating the area of a trapezoid is given by;

[tex]A=\frac{a+b}{2}h[/tex]

where a and b are the base and h is the height

From the question,

a = 5

b= 13

h = 3

substitute the vakues into the formula

[tex]A=\frac{5+13}{2}(3)[/tex][tex]A=\text{ 9}\times3[/tex][tex]A=27ft^2[/tex]
